136. Your customer calls complaining
that their modem randomly disconnects from the Internet even though
they have disabled all auto-disconnect features. The telephone company
has tested the lines and is certain that there is no unusual noise.
What option(s) should you look at first when troubleshooting this problem?

A. Verify that the modem in
plugged into a properly working wall jack

B. Enter the code to disable call
waiting in the modem's property screen

C. If the modem is external, replace
it with an internal model

D. Test the line with an inexpensive
tester to be certain the feed is analog and not digital

E. Verify that the IRQ setting
is not conflicting with another device

Explanation: Assuming that
the software configuration is ok, the next most likely cause would be
something at the physical layer, such as the phone cable or jack. Also,
it is possible that the IRQ setting is on a non-standard COM port setting,
such as 2 or 9. Since these two IRQs are "shared", it is possible that
another device is interrupting the bus thereby causing the modem to
disconnect.

137. If two or more hardware components
are listed on a vendors Hardware Compatibility List, you can be assured
that the hardware will perform as expected in the server

A. True

B. False

Explanation: Just because
specific hardware is listed on the HCL, this does not mean that the
devices have been tested together.

138. When a problem is first called
in, the first step in the troubleshooting process is to:

A. Check the status of the server(s)

B. Check the user's login account
name and password

C. Document the problem request

D. Scan for viruses

Explanation: Whenever a problem
happens, it is critically important to document it. Documentation will
save hundreds of hours over the life of the network, so start it early
and keep it current.

139. A user calls the help desk complaining
that they are not able to reach the Internet. The network consists
of 200 PCs running both IPX and TCP/IP. IP addresses are dynamically
assigned with a DHCP server on every segment. The results from the
Winipcfg utility appear to be correct and all required address are present
(IP, subnet, DNS, and default gateway). What else would be a logical
item to check?

A. The NetWare server has reached
its maximum number of licensed connections

B. The server has failed

C. Other users to see if anyone
is able to get to the Internet

D. The IP address of this workstation
has been assigned to another device on the network

Explanation: If others are
able to reach the Internet, then the problem probably exists with the
user's PC. However, if nobody else is able to connect the problem is
most likely in the router, physical connection link, or the ISP.

140. What are some common items that
need to be documented?

A. Default Printer settings

B. IP addresses

C. Screen saver settings

D. Desktop themes

E. Batch files and shortcuts

Explanation: IP addresses
are a must in an IP network. Printer settings also can be a nightmare
if not properly documented, as can batch files and shortcuts. The remaining
items are really not critical to the operation of the workstation or
network.
